How Cells Safeguard Chromosome Separation

The spindle assembly checkpoint helps cells safeguard chromosome separation during anaphase. It acts as a molecular surveillance system. The checkpoint checks whether the steps needed for chromosome segregation are complete before the cell moves on.

Many proteins work together to control this che...

The spindle assembly checkpoint is a surveillance mechanism that monitors the transition from metaphase to anaphase.

This checkpoint ensures that all chromosomes are correctly attached to opposite spindle poles on the mitotic spindle. The checkpoint delays the onset of anaphase until all chromosomes are bioriented, sensing the tension gen...
